Thus saith the LORD; Execute ye judgment and righteousness, and deliver the spoiled out of the hand of the oppressor: and do no wrong, do no violence to the stranger, the fatherless, nor the widow, neither shed innocent blood in this place.

But those that encamp before the tabernacle toward the east, [even] before the tabernacle of the congregation eastward, [shall be] Moses, and Aaron and his sons, keeping the charge of the sanctuary for the charge of the children of Israel; and the stranger that cometh nigh shall be put to death.

Therefore thou and thy sons with thee shall keep your priest's office for every thing of the altar, and within the vail; and ye shall serve: I have given your priest's office [unto you] as a service of gift: and the stranger that cometh nigh shall be put to death.
